Thetop 12 of the button This invention relates to carseals or the like and is particularly directed to seals of thischaracter which are self-locking as distinguished from those requiring aseal press for fastening the same.

The objects of this invention are to pro- Vide an improved self-lockingseal which may be cheaply manufactured and which will be effective inuse; to provide a seal having a cap or coacting member having means forengaging with said catches to hold the parts in locked position; toprovide a seal having locking members which are covered or pered with orunfastened without being broken and to provide such other novel featuresand improvements in construction as will appear from the followingdescription.

In the accompanying drawing illustrating this invention:

Figure 1 is a side view of a complete seal shown in locked position;

Figure 2 is an enlarged sectional view of the locking or fasteningmembers shown 1n partially engaged position;

Figure 3 is a sectional view simllar to Flgure 2 but showing the partsin engaged or fastened position;

Figure 4 is a plan view of a portion of the seal and button;

Figure 5 is a plan view of the cap or coacting engaging end;

Figure 6 is a sectional view showing a slightly modified form ofconstructlon; and

Figure 7 shows a further modified form of construction.

My improved seal as shown 1n the drawing, comprises a strip 8 which 1spreferably formed of metal and which has sealing or fastening members toform a closed loop. In the commercial forms for car seals these stripsare formed of tin about 1/8 of an inch wide. A button or projection 9 isprovided adjacent to one end of the strip and is preferably formedintegrally therewith. In the forming of this button the edges of thestrip are drawn in making recesses 10 which project in approximate] tothe base of the button and a short ta 11 is left projecting lockingbutton provided with catches, and a` pro tected so that the seal cannotbe easily tam isY preferably flattened so that the button ywill projectoutwardly as short a distancey as possible.A This hollow projectionorf-button has one or more tonguesor catches 13 in the sides thereof,`,these tongues beingformed' by cuti ting orslitting the 4sides of thebutton from the toptofthebottom and punching or cutf ist tingontsections'to form holes 14atthe lower .i

lends of the tongues. The lower ends of the tongues are bent outwardlybeyond theadjaf cent surface o f thel button.. and will :have a certainzamount of resiliency.` l

The strip 8 is provided With a hollowcap or' coacting. fastening memberfor Yengagement with the button 9. In the particular arrangement shownthis capl is formed-"ad-v jacent to4 the end 16 of the strip. Thisp0rtionof the stripV is then folded closely upon itself to provide acover or top 17 forthejopen cap' orV projection 15. Thiscover portionhas an inwardly projecting annular flange orbead ISMitting tightly intheadjacent end of the cap l5 `as. Vclearly shown in Figure 2; ThestripV 8 is again folded so that the cap or pro-l jection 15 will passthrough a hole 19 inthe strip and extend outfonv the opposite side inpositionlfor engagementwith the'button 9.

p The cap or Afastening member 15 .is turned inwardly at its loweredgeto provideflocking or fastening means for, engagement with the lowerends of the tongues or catches 18. V' `This inwardly "turnedflangejoredge 20 preferably extends around the inner circumference o f the `capand "fits closely against the base or largest diameter of the button"V V`IVhen theseal is to be fastened or locked,` the vc-"apl isvbrought'intoengagement with the button preferably' as shown Vin Figure' 2,' one sideof the cap'being placed over thev but` ton until the edge or flange 20engages with the lowerendof the outer tongue 13, and then the button Visrocked,` or svtfungI downwardly until the opposite portion of the flangeengages with thetongue orcatch 13 on the op-l posite sideof the button.:VVhenvv the parts are thus brought into fastening or locking rela#tionas shown Vin Figure Sit will be practical= ly impossible todisengage such fastening members without breaking the seal. f It will.

yof the button.

Ybroken off as it'onlyhas short connecting portions uniting it with thebutton. The cover 17 fully protects the upper portion of the button sothat it release the tongues from engaging position. Furthermore afterthe iiange or rim fastening position the lower ends of the tongues willextend over thev same' so that it will be diilicult to disengage thetongues byrreaching through the open bottom or end However, the endsther protected in the device shown inFigure 6 by merely making slits tosever the lower ends and leaving oppositely disposed sections 21 of thelsides of the this figure. These sections will further prevent thepossibility of tampering with the tongues by means of any tool insertedvin the button. e

In the device shown in Figure 7 this yoint is further protected vso thatthere cou d be no ossibility of tampering in this manner. In t isarrangement the button 23 is formed adjacent'to one end of the strip 24and a fold made to provide a for the button. This cover portion has aninwardly projecting annular .flange 26 similar to the iange 18 shown inFigure 2. Another fold is made in the strip and the button is passedthrough a hold 27 in the strip 24: thereby making three layers of thestrip adjacent to the button. When a locking cap suchas the cap 15 isbroughtinto engagement with this type of button, the ends of the tongues28 will be fully protected both from the lower or underside and the topor cap side and the fastening or engaging portions lock the severalplies or layers at the respective ends of the strip so that the fastenercannot be disengaged without injuring the strip. While I have describedmy seal in connection with those of the car seal type, it will beapparent that various forms may be made for dierent purposes andtherefore I do not lwish to be limited to the particular arrangement orconstruction shown and described except as set forth inthe followingclaim in which I claim: 4
